Description

Technical Field

[0001] The utility model relates to the technical field of molded structures of medical supplies, in particular to a molded structure of an elongated thin-walled sheath with high efficiency and quality. Background Art

[0002] The molding structure of the elongated thin-walled sheath is used for high-quality and efficient manufacturing of medical monitoring sheaths. The sheath is a disposable sheath with a slender and thin wall and is used for anal detection. During injection molding, the molding structure is prone to eccentric leakage. Although there is an anti-eccentric structure, the effect is not good. Moreover, the exhaust cooling effect is not ideal, and the defective rate of black spots, white spots and air leakage in the products is as high as about 50%, which has not been solved for a long time. The main reason is that the molding structure has the following defects. First, the supporting force of the cylinder for the support needle structure is not enough, that is, the anti-eccentric support is not strong enough, resulting in the support needle retreating and support failure. The bottom of the product is too thick, and when the glue is uneven, it is easy to cause side holes, which makes the medical detection sensitivity low. In addition, during injection molding, the center of the filling flow end is not fully exhausted, the product is burnt, and there are many defects, which do not meet the quality requirements. Second, side cooling, one side of the annular sheath is unevenly cooled, the injection molding glue deviation is large, the molding needle is eccentric, and the product is defective. Third, there is no clamping column in the glue flow channel, which is not convenient for the robot to clamp the flow channel, and semi-automatic injection molding cannot be realized, and the efficiency is low. In order to solve the above defects, we propose a molding structure of a high-efficiency and high-quality long thin-walled sheath. Utility Model Content

A cylinder 3 is fixedly installed in the middle of the front surface of the first fixed plate 1, wherein the cylinder 3 adopts a suitable large cylinder, which can provide sufficient supporting force for the supporting needle structure 5 to prevent support failure. The output end of the cylinder 3 passes through the first fixed plate 1 and is connected to the supporting base plate 4, and the supporting needle structure 5 is fixedly installed on the rear surface of the supporting base plate 4. A thin-walled elongated molding needle 6 is fixedly installed on the surface of the second fixed plate 2, and an annular cooling molding structure 7 is fixedly installed on the front surface of the second fixed plate 2. The thin-walled elongated molding needle 6 is arranged behind the annular cooling molding structure 7 and passes through the second fixed plate 2 and is embedded in the interior of the annular cooling molding structure 7.
